Our new paper titled "HVAC load synchronization in smart building communities" has been published in "Sustainable Cities and Society" journal. This paper has been wrote by Ali Ghofrani and Seyyed Danial Nazemi under supervision of Prof. Mohsen Jafari.
In this paper, we proposed a methodology to assign HVAC operation planning schemes for connected buildings with the objective of energy saving and load leveling. The idea was to use building thermal inertia in a periodic pattern by relaxing the temperature setpoints to an upper bound and setting back to a lower bound to avoid air conditioning while the room is still within human comfort zone. This periodic operation planning in turn facilitates the collaboration across a building community to reduce the aggregate demand. In this work, the objective was to assign periodic temperature setpoints for a building cluster so that the aggregate cooling electric demand reduced with the minimum cost and less load variations. Several setpoint scheduling policies were studied and applied on validated building simulations with different functionalities. The impact of periodic temperature scheduling parameters on various building types and different combination of building communities were evaluated thoroughly. Ideal schedule forms were identified and elaborated in detail. Human comfort level and demand-side management applications were also evaluated and incorporated into an optimization framework. The impact of peak demand reduction on the grid and power generation costs was also evaluated.
